I see sound bars with HDMI in and out as well as Receivers. https://answers.yahoo.com/question/index?qid=20131209212942AAZtI6z covers this as well.
I have what appears to be a unique situation. I am attempting to set up a projector with a sound bar in my living room. The audio/video source is a PS4 (equipped with audio optical output), and the video will be HDMI into the projector.
I cannot get cable to the projector location, which lead me down the wireless path.
The challenge I am facing is finding a component that accepts audio optical in, and will transmit to the sound bar. I have tried scouring the internet for bluetooth components and most recently looked into Sonos Hi-Fi to take advantage of the Wi-Fi network. All dead ends.
If Sony would open the native Bluetooth capabilities on the PS4 allowing me to pair a sound bar, my problem would be solved.
Anyone have any ideas?
